Project description:

The extremely rapid growth of fattening hybrids used in conventional chicken fattening is a major contributor to a number of common animal health problems. In organic farming, therefore, only slow-growing animals are to be used in accordance with EU organic regulations. To date, however, there has been insufficient information on the health status of different slow-growing breeds on organic farms. The aim of the project was to investigate and evaluate six different fattening strains with different growth intensities under practical conditions with regard to their suitability for organic chicken fattening. For this purpose, the main parameters used were animal health and economic efficiency (e.g. walking ability, plumage and skin condition, exit rates, fattening performance). The six origins were tested on a total of eight farms in two rounds. One provenance was kept on each farm throughout as a reference provenance. The results are intended to provide practitioners with information for the selection of suitable origins. Funded by the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV) via the Federal Agency for Food and Agriculture (BLE) as part of the Federal Organic Farming Program.
